Our factory is equipped with professional circular sewing machines, which feature: aesthetically pleasing appearance, smooth interior with fine workmanship, and a service life of over a million uses. The inner steel wire frame allows for free stretching and bending without deformation and is resistant to friction. Made from wear-resistant industrial canvas, our products offer high cost-performance and have received positive feedback from numerous customers. They are characterized by compact structure, ease of use, high distribution efficiency, and dust-free loading and unloading. They are not only used for automated or semi-automated unloading and loading of cement in storage facilities for cars, trains, and ships, but also for the bulk distribution of materials like coal powder, stone powder, aluminum powder, and food powders.

Flexible expandable connectors can be used horizontally or vertically. When used horizontally, they are typically made using a support ring technique, which ensures a uniform distance between the protective sleeve and the cylinder, reducing friction and extending service life. For larger stretch lengths, a metal ring can be added at each bend to enhance the stability of the sleeve. Installation methods are not restricted; they can be fixed with a flange or a collar band.
